...safety of removing the output caps...

I was (at least) one of folks who (long ago) removed DC blocking caps from my "vintage" JVC 1010 CDP with fabulous results. Here are a few key points:
1 - My down stream equipment definitely DOES have input blocking caps (I had the service manual for my amp).
2 - The cap was a large, generic electrolytic, probably more appropriate for a power supply than a signal path,
3 - Shorting it out was initially a quick and dirty (and reversible!) experiment but the results were so beneficial, I kept it that way.
My advise would be to (once you have verified no DC!!!) to temporarily try shorting out the cap with a temporary jumper (could even try spring hook-leads or small alligator clips) and see if there's enough difference to take a chance. If there is and you aren't sure about your down-stream status, you can try to pick an upgraded, audiophile cap (assuming it wasn't one to start with).
PS - On closer reading of your post, as long as you have DC coupling caps SOMEWHERE between the input and the speakers, it should be safe to remove the output cap. One simple check is to see whether there is any (temporary) displacement of your woofer when (carefully!!) adding or removing the short, since this is an indication of the presence of DC at the speaker.
Good luck! - Ted
